JACOB J. UNBEHEND, OF SYRACUSE, NEW YORK, ASSIGNOR- TO JUDSON L. THOMSON8: CO., OF SAME PLACE.

SHOE-CLASP.

SPECIFICATION forming part of Letters Patent No- 384,339, dated June 12,1888.

Application filed December '3, 1887.

To aZZ 1 0710772 it may concern/.-

Be it known that I, JACOB J. UNBEHEND, of Syracuse, in the county ofOnondaga, in the State ofNcw York, have invented new and 5 usefulImprovements in Spring Shoe-Clasps, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

My invention relates to improvements in [O spring-clasps adapted for useupon arctics,

overshoes, and the like articles, and the object is to provide a simple,efficient, and eco' nomicallyconstructed springclasp which will producethe desired result and shall be very t5 economically manufactured; andto this end the invention consists in the combination, in a springclasp,of a base-plate having its side edges bent substantially at right anglesto the main portion of the plate, and the bent parts provided withnotches or indentations for the reception of the tonguepivots, ahook-shaped tongue having cam or flattened pivots seated in the notchesor indentations in the angular edges of the base-plate, and a supportingspring-plate connected to the base-plate by suitable fastening means andbearing on the tongue, thereby retaining the tongue-pivots in thenotches formed in the bent edges of the base-plate, all ashereinaftermore fully described, and pointed outin the claims.

In specifying my invention reference is bad to the accompanyingdrawings, formingapart of this specification, like letters indicatingcorresponding parts in all the views, in which-- Figure 1 is an edgeview of my improved spring-clasp, illustrating the general constructionand arrangement of the parts, the holding tongue or lever being open forthe purpose of showing the operation of the spring- 0 plate on thepivots of the holding lover or tongue. Fig. 2 is alike view, in whichthe base-plate having the bent angular edges is reversed in constructionto that shown in Fig. 1; in other words, in Fig. 1 the base-plate is 5shown to be the upper plate, with the angular edges bent down andprovided with the pivotsockets, while in Fig. 2 the base-plate isunderneath, and the angular edges are bent up on the inside and providedwith the notches forming the pivot-sockets with the spring- Serial No.256,729. (No model.)

plate resting on the end of the hook-shaped tongue. Fig. 3 is anisometric view illustrating a further modification in which thebaseplate is constructed substantially similar to the form shown in Fig.1, excepting that the spring-plate is provided with coincidentforwardly-projecting arms hearing on the fiattened pivots of the tongue.Fig. et shows the blank of the baseplate, and Fig. 5 the springplate ofthe construction illustrated in Fig. 2.

(t denotes the baseplate provided with a forwardly-extcnding bifurcationand arms a. a. The arms a to terminate on their edges withsidewise-projecting extensions (1 d, having notches or. opposite ear'hother in the said extensions. The extensions d d are bent atsubstantially right angles to the main portion of the baseplate a, sothat the notches a project vertically and form seats for the pivots p ofthe hook-shaped'tongue t. The tongue t is provided with camshaped orflattened pivots 1), formed preferably from the material from which thetongue itself is struck up, and the said pivots p are seated in thenotches or indentations a in the base-plate, as shown at Figs. 1, 2, and3. In order to support the tongue on the base-plate, and to retain thepivots 1) thereof in their seat in the notches or indentations 12,1provide a spring-plate, b, having an extension or extensions, c, whichbear on the tongue and retain the pivots in the notches n.

The spring-plate b is provided with aslot,s, coincident with the slotsin the piate c,and the said springplate b is connected to the plate a.by any suitable fastening, as the eyelet-rivetj, Figs. 1, 2, and 8; butI do not restrict my in vention to the particular fastening meansshown,since any suitable fastening for connecting the two plates may beemployed. Neither do I restrictniy invention to the specificconstruction illustrated and described herein, since the angular edgesor extensions dd may be either on the outer edge of the base-plate a andproject downwardly, as shown 95 in Figs. 1 and 3, or they may be on theinner edge of the base-plate a and project upwardly, as shown in Fig. 2.The only difference would be that where the angular edges (1 61''project downwardly the baseplate a forms the upper [c0 plate of theclasp-frame, and the supportingspring b, with its extensions 0, bearsupwardly and supports the tongue from below, whereas in the othercase,where the notched edges dd project upwardly,the plate a forms theunder plate of the clasp-frame,and the spring-plate, with its extensionsc,loears against the tongue t.

The tongue or holding-levertishook-shaped, as best shown in the edgeviews, Figs. 1 and 2, and the laterally-projecting pivots p arecamshaped or flattened, so as to exert a strain on the spring-plate bwhen the tongue or holdinglever is operated in opening and closing theclasp, and the camshaped or flattened pivotsp correspond to the shape ofthe notehesnin the base-plate a,and the said notches n serve as thehearings or sockets for the said pivots of the tongue or holding-lever.

At Figs. 4 and 5 I have illustrated the detail construction of theblanks for the base-plate a and spring-plate b as employed in the claspshown in Fig. 2.

To construct the clasp as shown in Fig. 1,it is simply necessary to formthe blank shown in Fig. 4 with the notched extensions d d on the outeredges of the arms a a, instead of on the inner edges,as shown in thesaid figure,and the spring-plate I) may have two extensions, 0 c,coincident with the arms aaof the base-plate a. In either case, however,the extensions 0 c bear on the tongue 25, and thereby retain the pivotsp in the notches a.

WVhere the extensions 0 c of the spring-plate b are central, as shown inFig.5, the extension 0 bears on the hook-shaped edge of the tongue tmidway between the forwardly-extending arms a a of the base-plate, andwhere the free end of the spring-plate Z) terminates in two extensionscoincident with the arms a a the said hook-shaped portion of the tonguet. The clasp is simple in construction, compact, and effective for thepurpose intended.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a spring-clasp, the combination of a base-plate having its sideedges bent at right angles to the main portion of the plate and the bentparts provided with notches or indentations for the reception of thetonguepivots with the tongue having cam-shaped pivots seated in theindentations or notches in the angular edges of the base-plate, and asupporting spring-plate connected to the base-plate and retaining thetongue in the sockets on the baseplate, substantially as and for thepurpose set forth.

2. I11 a spring-clasp, the combination of two sheet-metal plates, a b,secured together at one end, the plate a bifurcated at its opposite endand provided with sidewise extensions bent at right angles to the plate,and having notches n n therein forming bearings for the tonguepivots,the other plate, I), having its free end terminating in extensions 0,which are adapted to rest against the base of the tongue orholding-lever and confine the tongue-pivots in their bearings in theplate a, the hook'shaped tongue-lever 15, its hook-shaped endconstructed with 1aterally-projecting flat pivots p, corresponding tothe notches n in the bent edges of the plate a, substantially as and forthe purpose set forth.

In testimony whereof I have hereunto signed my name, in the presence oftwo attesting witnesses, at Syracuse, in the county of Onondaga, in theState of New York, this 30th day of November, 1887.

JACOB J. UNBEHEND.
